Abstract

In this paper we study the problem of noisy tensor completion for tensors that admit a canonical polyadic or CANDECOMP/PARAFAC (CP) decomposition with one of the factors being sparse. We present general theoretical error bounds for an estimate obtained by using a complexity-regularized maximum likelihood principle and then instantiate these bounds for the case of additive white Gaussian noise. We also provide an ADMM-type algorithm for solving the complexity-regularized maximum likelihood problem and validate the theoretical finding via experiments on synthetic data set.

Abstract

In this paper, an alternative proof of results in [6] is given; there, the existence of T-periodic solutions of a family of Lazer-Solimini equations with state-dependent delay is studied. The tools used in the proof are a combination of a priori bounds and coincidence degree. En este trabajo se hace una demostración alternativa de los resultados [6], donde se estudió la existencia de soluciones T-periódicas para una familia de ecuaciones del tipo Lazer-Solimini con retraso dependiente del estado. Las herramientas utilizadas en la demostración son una combinación de cotas a priori y grado de coincidencia.
